pierre 6d2c35a332 Core/DSPCore: Jit: only end emitting the current block when hitting an
unconditional branch(or idle skip), emit check g_dsp.pc and return when
hitting a conditional branch.

pierre 47eb5c3416 Core/DSPCore: Only check for internal exceptions in DSPEmitter::checkException, but
call it for every instruction, like in DSPInterpreter::Step. Fix the analysis lookups
for DSP_IDLE_SKIP and DSP_LOOP_END.

After this patch, the block_size and the return value from the block always match,
except when an internal exception is detected. This will change in a later patch,
so we actually get some benefits from checking if we need to call HandleLoop().

pierre e9d91fb9f3 Core/DSPCore: Initialise all of the code blocks
It is pure luck that we did get a fresh (thus zeroed) memory area when not putting DSPLLE on thread. ClearIRAM() is supposed to only clear the non-static part.

pierre 34909ecebc Core/DSPCore: Make the JIT blocks return the number of cycles executed.
The block_size seems to be not reliable, even after trying to more closely match
the interpreter by looking at the analysis for (addr+opcode->size-1) for detecting
the end of the block.

Since we need to "calculate" this number shortly before returning to
RunForCycles, it seemed logical to use the (up to now) unused return value
of the blocks.

Improves SMG2 here.

pierre f3b144d563 Core/DSPCore: Fix register use in two (currently) unused functions, correct the
IsSameMemArea check in the rest of the file.

Looks like this is simply a copy-paste error, that i dutifully "fixed" for 64 bits.

No idea if this fixes anything, but it brings JIT more in line with the interpreter.

pierre aaeb21fe3b Core/Common: Automatically emit a MOV in ABI_CallFunction* when the function
pointer cannot be reached by 32bit displacement.

RAX is caller save and non-parameter in all 64 bit ABIs, so it should be safe
to clobber it on function call.

pierre b80e207a8a Core/DSPCore: Make JIT work on 64 bit hosts
This is the safe variant that does not assume other
functions use R11 for &g_dsp.r, which they actually do.
So there is a lot unnecessary reloading of the register
getting emitted.

There are a few small changes exploiting pointers known
at emission time and making use of MComplex math.

Also renames m_LLEplaying to m_AIplaying in Core/AudioCommon.

pierre ce1057f17d Core/AudioCommon: Feed bigger audio chunks to the output devices in case of underrun.
This should eliminate the crackling with alsa and pulseaudio backends and replace it
with much nicer pauses. This is only interesting for audio backends that do not
respect Mixer::GetNumSamples() and should not impact users able to run the DSPLLE at
full speed.

The cost of this is an added LLE audio latency of about 0.06 s in the continuous
playback case. If that is too much, lower the low watermark.

pierre bc1e0c24e8 Add an PanicAlert in case we try to do an >32 bit displacement
If you see this alert, dolphin will probably crash in a few moments.

Found in the course of fiddling with DSPLLEs JIT, which puts its data
structures and static code somewhere above 0x7fff00000000 on my machine, making
it unreachable via 32bit displacements from the created code at ~ 0x40000000.

Fixed all the offending places in DSPLLEs JIT to emit register indirect accesses,
only to find out that the generated code is slower than the interpreter and does
work just as good(or bad). Oh well, back to DSPHLE it is then.

pierre 91036ae160 Slightly adjust z-values calculated in the vertex shader so OGL does not clip the
final rendering of (at least) Sonic Unleashed.

This should be (nearly) invisible in Z16 depth copies and in games, but there is
some chance that it collides with other such border cases. There probably is some
room to decrease the adjustment but 9999999/10000000 is not enough. A static offset 
may be an option, too. I don't know if the game can/does set something like that.

pierre 6583a3f1e2 Plugin_VideoOGL: X11: Add another display connection to keep the two threads from
eating each others events.

Manifests itself in GPU thread waiting forever for a reply in GL library code(and thus 
a frozen emulation). Most of the time, this can be resolved by creating more events 
(clicking, changing focus), but sometimes it stays stuck.

pierre 236f75aac3 Make shader for copying from depth buffer to texture more resilent against precision loss.
The theoretical result is slightly different to the original shader because the
final adjustment is to the range [0/255..255/255] instead of 
[0/16777215..16777215/16777215].

The real result is vastly different on some gpus that were giving incorrect results
of bits 23..16 (y-component) wrapping around while bits 31..24 (z-component)
stayed the same, and bits 31..24 changing while in the middle of the value range
for bits 23..16 for large depth values.

This should fix issue #3123.

pierre 468b9bfe68 Fix the OpenGL depth buffer values from the vertex shader.
I am not sure i am understanding what the pipeline really does, and more so what
the GC/WII expects here. If my comments are incorrect, please let me know.

This was tested with MP2:E, ZWW on r6075.

glxMakeCurrent is supposed to error out when the context is
still current in another thread. NVIDIA handles that, but mesa3d errors.

pierre 714af087bf GL: Relax multisampling constraints on visual
All visuals with parameter GLX_SAMPLE_BUFFERS_ARB = 0 have
GLX_SAMPLES_ARB = 0, so the old code would only ever choose
visuals with GLX_SAMPLE_BUFFERS_ARB>=1 and GLX_SAMPLES_ARB>=1.
Some drivers do not export any multisampling capable visuals,
so dolphin fails to find a matching visual and falls back to
the single buffered visual(which does not work for some yet
unknown reason). Fixes issue #2647.

pierre b73b77014f Rework the logic for avoiding lerp() in shader code
This should give the exact same shader code except for the cases of
SELA == SELB and SELC == 1, the latter only for the color combinder.
In these two cases the results of the shader should not change in any way.

It would have been possible to optimize the SELC == HALF case too, if
the actual factor had been 0.5f instead of 0.4980392f.

pierre e07a91930d The result of the last texenv stage is used regardless of destination register
The real hardware probably always sends the result of its computations
to the alpha test/fog units, in parallel to its registers, but those
only take the result of the last texenv stage.

This makes grass show up in ZTP, where the last texenv stage oddly writes to
reg #3 instead of #0.

pierre ab89decac5 Linux: Better ALSA support
This removes some bad behaviour, like the audio thread busy waiting inside ALSA code,
missing begins of voice samples(due to DSP_HLE code not getting called often enough).
Turns out my understanding of ALSA API was lacking.

Tested with pulse plugin and directly on my intel-hda/realtek hardware.

pierre 39b17ca640 Linux: Fix horrible latency when the alsa pulseaudio plugin is involved, see issue #2651
The fix is asking alsa for a prefered "hardware" buffer size, so alsa does not fall
back to pulseaudios offering of ~1 minute. Additionally, alsa busy waits when pulseaudio
is used, sw:avail_min is set and hw:buffer_size is small.
